paths-data-01-t

Test that the viewer has the basic capability to handle the 'path'
element and its data (d) attribute in combination with the cubic
Bezier curveto commands, C, c, S, s (plus Mm and Zz).

There are 8 subtests, each composed from the cubic Bezier path commands per
the label by the subtest. On-curve control points (i.e., the curve position)
are marked by small blue squares. Subtests are filled, or stroked, or
both, using simple style properties and colors.

The rendered picture should match the reference image exactly, except for possible
variations in the labelling text (per CSS2 rules).
